Roofdrain Outlet (TPE) Perforated 240mm High 40mm Diameter Black Wallbarn

Roofing Superstore

TPE is a compound of rubber and polypropylene, developed as a cost effective way to waterproof and protect drainage holes and outlets on roofs and balconies in conjunction with bituminous waterproofing membranes. The material is tough, flexible and durable. The resilient TPE material is UV stable and resistant to deterioration by normal atmospheric elements and ground salts. It can withstand temperature of 120C and will not become brittle at very low temperatures. These outlets, collars and vents are ideal for SBS and APP bituminous membranes, including built-up (felt), mastic asphalt, hot melt and other liquid applied membranes such as Fibreglass. The circular drain connector is used for downpipes and outlets on a roof or terrace within the main body of the concrete deck. Made from TPE, these outlets are for use where a circular hole is cast into the concrete deck. The area is fully waterproofed around the hole and into the hole with a first layer / coat of membrane. The connector is then inserted into the hole, and a second coat / layer of membrane is installed on top of the flap (flange). The connectors are manufactured with a perforated flange so the membrane oozes through to bond to itself in a sandwich situation, ensuring a very secure bond. The shank s 240mm long and is designed to fit inside an HDPE pipe tightly. The shank or pipe is manufactured to a slight cone shape, making it easier to press into the hole and helping to prevent the connector rising out of the hole. There are two rings on the shank which help to ensure that as it is pressed into the hole no water can pass back up the pipe, acting as a further drain trap. At the mouth of the shank there are a series of ribs and serrations along the inside, which ensure a leaf guard or gravel-excluder can be fitted into the connector securely. The connector should not come into direct contact with the bare concrete, as this risks the chance of water passing beneath the rubber profile and ingressing into the structure. The connector sits between two layers of waterproofing. For two coat liquid applied membranes this can be achieved fairly easily without disrupting the waterproofing process. For sheet membranes the best practice is that an additional layer of membrane should be applied and adhered to the area. The first layer can be installed and fully bonded, the outlet is inserted into the hole, then a patch of membrane is fitted above and around the outlet. It should be fully bonded to the flange of the outlet and the first layer of membrane by adhesive or heat-bonding to achieve a fully watertight bond. TPE - for use with bituminous felts & asphalte. Flange with holes - perforated. Height: 240mm.. Roofdrain Outlet (TPE) Perforated 240mm High - 40mm Black Wallbarn

Measuring 240mm long and featuring a 40mm pipe diameter, this perforated roof drain outlet from Wallbarn is made of flexible and strong TPE (Thermoplastic elastomer). It works to add a waterproof element to drainage holes on both balconies and roofs that are already equipped with bituminous waterproofing membranes. With resilience to weathering and UV rays, this outlet can withstand temperature changes up to 120C and resist brittleness in lower temperatures.Where holes are made in concrete decks, this outlet is easily installed after a layer of waterproof membrane and then coated with a second layer on top of the flange - which has a perforated edge for the membrane to settle in for a secure and sturdy bond. The 240mm shank fits into an HDPE (High-density polyethylene) pipe snuggly and is slightly coned to ease the fit and provide additional stability. Water is prevented from travelling back up thanks to the two rings that emulate a drain tap, and the serrated area allows for a drain guard to join the system.Features & Benefits: Roofdrain Outlet (TPE) Perforated 240mm High - 40mm Diameter, Made from TPE (Thermoplastic elastomer) for durability, resilience, and waterproofing, Installed alongside two layers of a waterproofing membrane, Perforated flange to help bonding, Coned shank with serrated area to ease installation and allow for drain guards, UV stable and able to withstand high (120C) and low temperatures.Compatible with SBS (Styrene Butadiene Styrene) and APP (Atactic Polypropylene Membrane) membranes, such as built-up (felt), hot melt, mastic asphalt, and other liquid-applied membranes.Please note: , Do not allow direct contact with concrete as this can allow water to find its way beneath the outlet and cause damage., Assure that a layer of membrane is fully bonded to the outlet flange and the first layer for completely watertight bonds..
